McAfee acknowledges that Faull had complained about his dogs, which were poisoned shortly before Faull's killing, but McAfee has said he didn't kill him.

The former tech-company founder has talked about his case with reporters via email, on cellphone calls from undisclosed locations, and in his blog, "Who is McAfee? The official blog of John McAfee."

McAfee, the creator of the McAfee antivirus program, has led a life of eccentricity since he sold his stake in the anti-virus software company that is named for him in the early 1990s and moved to Belize about three years ago in an apparent effort to lower his taxes.

A source at the U.S. Embassy in Belize told AFP people close to McAfee had denied reports that he was captured. A police spokesman told the news agency he had no information on a possible arrest.
